Doucai 'Chicken Cup': Is it antique or just a reproduction. Thanks for your help.

I'm afraid I cannot help. This type of porcelain is one of the best known and most expensive ones worldwide. I could not possibly tell if it is a fake if the copy is very good, but please compare the green of the leaves with those of authentic pieces. Doucai wares of the Ming dynasty were generally light in color, especially the green of the leaves. 
Look at this: https://en.wikipedia.org/wiki/Chicken_Cup_(Chenghua)

It is virtually impossible to find an authentic Ming Chenghua chicken cup in the open market, but scores of fakes exist. That is why we see them at all. The real cups are auctioned in the millions and this always results in lots of fakes.

Thanks a lot for your help, and thanks for the links.
After comparison with the authentic pieces, neither the designs nor the colors match. Especially the green of the leaves.
Thank you again for your help.
